The Roswell Report: Fact versus Fiction in the New Mexico Desert was published in 1995 by Headquarters United States Air Force. It was written in response to Representative Steven H. Schiff's request and a General Accounting Office audit, and it contains Col. Richard L. Weaver's report and 1st Lt. James McAndrew's synopsis, along with attachments, appendices and photographs. The report says researchers found no evidence of an extraterrestrial craft or crew. It concludes that the 1947 debris came from a Project MOGUL balloon train.

AM-1 Transmitter
10.
Frequency ranges :from 1.$ to 9mc can be employed with the A.t+-1.
The modulation ot the AM-1 is effected by use of' a triode modulator
. (2-.3A5) tubes) connected in series with the plate supply of a class
"C" RF amplifier. Variation of' the plate supply voltage of' the
RF amplifier caused b~r change in tube resistance gives amplitude
modulation linear with plate voltage of the anplifier. By use
ot this system modulation from DC to several hundred cycles is
obtained.
The receiver tor this transmitter was a Hammerlund SP 400X with
several modifications. In order to increase the signal to noise
ratio a crystal filter was introduced into the IF amplifier
circuit to narrow the bandwidth. Bandwidth was also reduced by
